Twitter has launched a new feature called "Moments'' that helps highlight the top stories being tweeted.

The feature will showcase top stories being discussed, even if you don't follow the tweeters. It can be found by tapping a lightning bolt icon tab on the site or app. It will update the "Moments'' throughout the day.

Twitter, which limits posts to 140 characters, has been trying to find a way to make the site easier to navigate and broaden its appeal beyond media junkies, athletes, celebrities and politicians. The short messaging service has amassed more than 300 million users but its growth has been slowing.

Meanwhile, Facebook has 1.5 billion people on its online social network and even its photo-sharing application, Instagram, has surpassed Twitter in size.
